IMPRQVEMENT' IN MILK-dooLERS.

l The Schedule referred thin these Letters -Patent making part of the same.

To allvwhom (it 'ma/y concern .j

Be it known that we, ASAPH THOMPSON, of the town of Hudson, inthe county of Summit, and State of Ohio, and J Mns DABLING, of the township of Northfield,

county and State aforesaid, have inventeda new and l,useful `lYIilk-Clooler, called Thompson and Darlings Buckeye Milk-Cooler for Cheese-Factories, for cooling milk and other liquids pand we do hereby declare that, the following is aflill andv exactdescription of 'the construction `-and; operation vlof v'the same, reference being had to the 4annexed drawings, and the letters of reference marked thereon, making a part of this specicatiou, in whichl,

Figure I' represents the pipes, through which the 'cooling-liquid flows, detached from the vat or reser' voir containing the liquid to be cooled, with the floats attached (in one style) to the pipes; and I, in said figure, is the induction-pipe, through which the cooling-liquid enters the pipes.

P P P P P, the pipes, arranged, in the iigure, in parallel lines, for rectangular vats or reservoirs, but

` the shape of which is determined by and adapted always to the form of said vats. D is the discharge-pipe. F F F F are the floats, which support the pipes in the vat.-

These may be made of any size, shape, or material,

' -and `may be placed below, or between, or at any distance above the pipes, according as the pipes are used on or at a greater or less depth beneath the surface of the liquid-to be cooled.

-T T T T are the tubes or'fauoets, to regulate the amount of air in the oats, andthus lower the pipes in the vat.

Figure H represents one ofthe oats detached, in

which T is the' tube to'regulate the amount of air in the; lfloat, and thus control its supporting-power. 'In plaoe of this tube, with its cock, a faucet, or any other equivalent device may be used. These may be made of dilerent materials, and placed in different positions, as hereinbefore stated.

' The gure represents one made of tin, air-tight,

open at the bottom,'and standing upon its side.

Figure 1H represents the pipes in position in the vat, and ready for'use.

Ris the reservoir, for containing the supply, in

quantity, of the cooling-liquid, as water, or Water and ice. Y

T', the tube or pipe, leading from the reservoir` to 'the induction-pipe I.

' This tube is made of flexible material, as India rubber, to accommodate itself` to the varying heights of the pipes.

P, 86e... are thepipes. F, 8vo., are the oats. D, the discharge-pipe. V is the vat, containingthe liquid tobe cooled. F', the frame supportingthe vat. O is an opening, into which the water falls from the discharge-pipe, and iiows back beneath the vat, andV escapes at the other end of the frame.

The operation of this invention is as follows Into the vat V the milk is put. Then the pipes are inserted, and the cooling-liquidis set toowin g through them, the pipes being, by means of the ioats, kept upon for the cooling-liquid to flow through, with the floats F F, 85e., or their equivalents, substantially as and for` the purpose set forth in the foregoing specication.

2. The mode of cooling liquids, by horizontal pipes, or'their equivalents, kept iioating on or at any desired depth beneath the surface of the liquid tobe cooled,

,the pipes adjusting themselves to the varying height ofthe liquid to be cooled, and having constantly dowing through them the cooling'fliquid, substantially as herein set forth. 1
